According to a hospital source, the former Los Angeles Lakers player remains in a coma. Lamar still has a breathing tube ventilating his lungs, and a feeding tube is supplying him nutrients. Doctors have been pumping the athlete via IV with clot-busting medication to prevent further strokes. "He hasn't suffered any more strokes," a source tells E! News exclusively, adding that his brain swelling hasn't worsened. "But he's not getting better and that has everyone worried."

Doctors have indicated to the family that the longer Lamar remains unresponsive, the less likely he may have normal brain function if and when he wakes up. As such, the family was also told to prepare for "everything," including a protracted stay in the hospital. The basketball player's family was told that because he likely suffered multiple strokes, he could have severe physical and mental impairment, including inability or trouble doing things like speak, walk and swallow.

If Lamar's coma persists long-term, he will have to be transferred to another facility that provides special rehabilitative care. Because a judge in L.A. has not signed off Lamar's divorce from Khloe due to a backlog in the system, the E! reality star is still in charge of making medical decisions on his behalf. He does not have an advanced health care directive in place stating his wishes regarding whether he wants to be kept alive by machines should he remain comatose.

As Lamar's friends and family have taken to social media to ask the world to pray for his speedy recovery, Khloe has remained publicly silent as she stands by the man she once called her "soul mate." Behind the scenes, she paid for Lamar's father, Joe Odom, and Lamar's kids, DestinyOdom and Lamar Odom Jr., to fly into town. Meanwhile, Kobe Bryant has also visited Lamar in the hospital.

Although Khloe had cut off contact with Lamar over the summer, a source told E! News Tuesday that she's been "completely inconsolable" since his hospitalization.
